Large malpractice claims databases are increasingly used as a proxy to assess the frequency and severity of diagnostic errors. More than 5,300 closed claims with at least one diagnostic error were analyzed. No singular factor was identified; instead multiple contributing factors were implicated along the diagnostic pathway.

This direct observation study examined maternal and neonatal care at 10 labor and delivery units. Investigators uncovered three environmental needs that impact safety: rapid access to blood products, space for neonatal resuscitation, and organization and availability of equipment and supplies. They conclude that applying design thinking to physical space could improve maternal and neonatal safety.

Most safety improvement interventions in obstetrics do not reflect insights from anesthesia providers. This commentary discusses how one hospital drew from the patient safety expertise of anesthesiologists and used simulation and communication interventions in its labor and delivery unit.
